Peritoneoscopy as a diagnostic supplement to liver function tests and liver scan in patients with carcinoma.

Liver function tests, liver scintigraphy and peritoneoscopy were carried out in 240 patients with carcinoma. Hepatic invasion was demonstrated by peritoneoscopy essentially when both of the other tests were positive. However, in one-third of the patients, peritoneoscopy revealed the presence of other pathologic changes which could account for the positivity of either of the other diagnostic procedures. The status of the liver, with regard to presence or absence of metastases, could be microscopically documented in 59 patients. False-negative findings of liver chemistry tests, liver scan and peritoneoscopy were seen in 27, 42 and 36 per cent, respectively, of the patients while the rate of false-positive results was 15, 10 and 3 per cent, respectively. The rate of false-negative peritoneoscopy examinations in the absence of simultaneous positivey of the two other investigations was insignificant. These data indicate that liver chemistry tests, liver scan and peritoneoscopy play a major and complementary role in the screening of patients with carcinoma.

Liver damage after paracetamol overdose. Comparison of liver-function tests, fasting serum bile acids, and liver histology.

54 patients have been studied after paracetamol (acetaminophen) overdose. Liver-function tests and fasting serum bile-acids were measured daily; liver biopsy was done in all cases, and slides were examined "blind" to assess liver damage. The plasma-paracetamol was measured on one occasion. A histological abnormality was present in the livers of 53 of the 54 patients, and was minor in 23, moderate in 16, and severe in 14. In 6 patients with moderate and 18 with mild histological abnormality liver-function tests were normal. A serum-aspartate-aminotransferase above 400 units/1 was always associated with severe histological liver damage. Fasting serum bile-acids were raised in 51 of the patients with abnormal liver histology; the serum-bile-acid seemed to be a more sensitive indicator of mild liver-cell damage than was the transaminase level. There was, however, little correlation between increase in bile-acid concentration and the degree of histological abnormality. As a result of these investigations empirically determined levels of plasma-paracetamol have been drawn which give a guide to the likelihood of liver damage after paracetamol overdose.

Serum bile acids and rountine liver function tests in patients with chronic liver disease and cholestasis.

Serum bile acids were measured in 28 patients with established liver disease. The peak serum level after a meal was as sensitive an index of liver disease as a combination of serum bilirubin, aspartate amino transferase, alkaline phosphatase and gamma glutamyl transpeptidase and was more often abnormal than any one of the four tests. Serum bile acid measurements may be of most value in detecting cirrhosis when the activity of disease is minimal.

Predictive values of various liver function tests with respect to the diagnosis of liver disease.

A prospective study of 181 patients suspected of having liver disease was carried out to determine the relative efficiencies of serum bilirubin (total and direct), alkaline phosphatase (AP), gamma glutamyl transferase (GGT), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) with respect to diagnosis. Liver biopsies, liver scans, abdominal ultrasound, and clinical parameters were also tabulated and used independently to evaluate the patient's hepatic status and to determine the final diagnoses in each case. From the results of these tests for the 60 patients who were diagnosed as having liver disease, and the 87 patients who were felt to be free of liver disease, predictive values of the above tests were established. Data from this study suggests that while direct bilirubin is the most specific test, GGT is the most sensitive and has the fewest false negatives in the diagnosis of liver disease.

[Bile acid concentration in serum after a test meal in hepatobiliary diseases. A comparison with quantitative liver function tests].

The concentration of bile acids in serum was measured by an enzymatic-fluorometric method under fasting conditions and 2 hours after a standardized meal in 26 patients with chronic liver disease (chronic hepatitis, liver cirrhosis, primary biliary cirrhosis) and compared with other tests of liver function. Postprandial bile acids and transaminases were false negative in only 12% and are thus the most sensitive tests after the BSP-retention test (3% false negative results). In comparison, fasting bile acids proved to be a relatively insensitive screening test for liver disease (38% false negative results). Postprandial bile acids were more closely correlated with BSP retention and BSP disappearance rate constant (Ki) than fasting bile acids. In view of these findings postprandial serum bile acid concentrations should be preferred to fasting bile acid concentrations in screening for liver disease and monitoring liver function.

Benorylate: a report on 2 years' experience of its use in rheumatoid arthritis and other chronic rheumatic diseases.

52 outpatients with rheumatoid arthritis or osteoarthritis were given benorylate (as the 40% suspension) in doses of up to 8 g daily. Peroids of medication were varied but some patients were given the drug for nearly 2 years. Assessments of clinical progress were made at regular intervals by recording both subjective and objective measurements including duration of morning stiffness, grip strength, joint size. Laboratory investigations include renal function tests, liver function tests, blood picture and occult blood. No serious side effect, attributable to benorylate was reported and it was concluded that the drug is satisfactory for the long term treatment of rheumatic diseases.

Liver function tests among Michigan and Wisconsin dairy farmers.

Serum activity of SGOT, SGPT, LDH, and alkaline phosphatase was measured in 614 Michigan adults exposed to PBB and 141 Wisconsin adults not so exposed. The Michigan group had higher prevalence of abnormal SGOT (p less than 0.005) and SGPT (p less than 0.005). A clear sex difference was observed. Michigan men had a higher prevalence of abnormal SGPT (p less than 0.005) and LDH (p less than 0.005) than Michigan women, and a higher prevalence than Wisconsin men of abnormal SGOT (p less than 0.005) and SGPT (p less than 0.01). These differences could not be ascribed to differing patterns of alcohol consumption, laboratory error, or choice of criteria for normality/abnormality. Seven Michigan subgroups were defined on the basis of the criteria by which they had been selected to participate. The two subgroups who were essentially self-invited did not differ from the remaining five randomly selected subgroups combined in prevalence of these abnormal liver function tests. Based on 364 serum PBB analyses thus far analyzed of the 614 Michigan participants, no obvious relationship between serum PBB values and liver function tests was observed. However, this is a tentative conclusion that will be further evaluated when remaining serum PBB analyses are completed. The greater prevalence of abnormal SGPT and SGOT among Michigan dairy farm residents compared to the Wisconsin dairy farm residents is tentatively ascribed to the former group's exposure to PBB.
